Description
Mercuric nitrate monohydrate, also known as mercury(II) nitrate monohydrate, is a white crystalline or powdery substance with a density of 4.3g/cm3. It is soluble in water and nitric acid but insoluble in alcohol. MERCURIC NITRATE, MONOHYDRATE is stable and hygroscopic, and it decomposes upon heating. It is also incompatible with organic materials, powdered metals, petroleum hydrocarbons, hypophosphoric acid, unsaturates, and aromatics, which can lead to violent reactions.
Uses
Used in Chemical Synthesis:
Mercuric nitrate monohydrate is used as a reagent in the preparation of other mercury compounds and in organic synthesis. It serves as an oxidizing agent, playing a crucial role in various chemical reactions.
Used in Analytical Chemistry:
MERCURIC NITRATE, MONOHYDRATE is utilized as an analytical standard for mercury, helping to determine the presence and concentration of mercury in different samples.
Used in Laboratory Research:
Mercuric nitrate monohydrate is employed as a nitrification agent and as analytical reagents in laboratory settings. It is also involved in the preparation of mercury fulminate, an explosive compound.
Used in Organometallic Chemistry:
The reaction of mercuric nitrate with acetone results in the formation of an organometallic compound containing mercury, which has potential applications in various chemical processes and materials development.
Preparation
Mercury(II) nitrate is prepared by dissolving mercury in excess hot concentrated nitric acid. Upon evaporation of the solution, large colorless deliquescent crystals of monohydrate, Hg(NO3)2?H2O, form.
It also is obtained by boiling a solution of mercury(I) nitrate or by the action of light on mercury(I) nitrate:
Hg2(NO3)2 → Hg + 2HgNO3
Reactions
Gentle heating of mercury(II) nitrate gives mercury(II) oxide evolving nitrogen and oxygen:
Hg(NO3)2 → HgO + 2NO2 + ? O2
However, on strong heating, mercury nitrate decomposes to mercury metal:
Hg(NO3)2 → Hg + 2NO2 + O2
When excess alkali hydroxide is added to a solution of mercury(II) nitrate, a yellow precipitate of HgO is obtained.
Addition of potassium thiocyanate solution forms a white precipitate of mercury(II) thiocyanate:
Hg2+ + 2SCNˉ → Hg(SCN)2
Addition of a small amount of alkali iodide to mercury(II) nitrate solution precipitates mercury(II) iodide:
Hg2+ + 2Iˉ → HgI2
Similarly, mercury(II) cyanide precipitates upon the addition of potassium cyanide to mercury(II) nitrate solution:
Hg2+ + 2CNˉ → Hg(CN)2
Toxicity
Mercury(II) nitrate is highly toxic by ingestion and possibly other routes of exposure. The LD50 oral for the dihydrate in mouse is 25 mg/kg.
Check Digit Verification of cas no
The CAS Registry Mumber 7783-34-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7783-34:
(6*7)+(5*7)+(4*8)+(3*3)+(2*3)+(1*4)=128
128 % 10 = 8
So 7783-34-8 is a valid CAS Registry Number.
